Of course if desiredY this method ofapplying the tire may be used regardless of Whether the tire is used onthe rear carrier or in the fender Wheels.

I preferably make the parts 1 and 4 of the cover of thin sheet metal sothat they `can be painted, enameled or plated in any Way to match orcontrast with 'the decoration of the automo-` bile. In some cases it isdesirable to chromium or nickel plate both of the parts or one of themonly, the remaining part being painted or enameled. I

Also if desired, the parts 1 and 4 may be made of stii non-metallicmaterial such as fibre board, or bakelite reinforced by fabric'such asused for panels for radio sets, but it Would be of much liner materialto make them ilexible, particularly.V

the tread ring.

Various other fastening devices maybe used to draW-.the treadring inplace, such as a turn buckle, Without departing from the spirit of theinvention.

I-Ia'ving described my invention, what I claim 1s:

1,. In tire covers, a round metal side piece adapted to cover one sideof a tire, a transversely splitmetal hoop adapted to cover the tread ofthe tire, said hoop having circumferential cor- .rugationa the outsideedges of which extend downwards to extend over the periphery of saidside piece and the opposite edge of the tread of the tire, a leverfastened to one end of the hoop .anda link having one end fastened tothe 'otherend of said hoop and the other end to said lever.

2. In tire covers, a round metal side piece adapted to cover one side ofa tire, a transversely split metal hoop adapted to cover the tread ofthe tire and to extend over the periphery of said side piece, leverspivoted to the open ends of said hoop there being a plurality of holesin said levers, a pin passing through said holes, and a handle securedto one of said levers and adapted to engage the hoop when said pin isbelow the center line joining the pivot points of the levers to hold thehoop and side piece on the tire, said plurality of holes permitting.adjustment to t the cover to Varying sizes of tires.

3. In tire covers, a round metal side piecey adapted to cover oneside ofa tire, a transversely split metal hoop adapted to cover the tread oftheY tire and to extend over the periphery of said side piece,` a pairof ears secured to each endlof the hoop, a U-shaped lever having itsfree ends pivoted to one pair of ears, levers pivoted vto the other pairof ears and a pin securing said last vmentioned levers to the firstmentioned lever, said pin being positioned below the center line joiningthe pivot points ,when the cross piece of the U-shaped levers engagesthe hoop. Y

4. In tire covers, aY round metal side piece adapted to cover one sideof .a.ti1'e, a transica versely split metal hoop adapted to cover thetread of the tire and kextend over the periphery of said side piece,U-shaped straps having their ends extending through the hoop adjacenteach end and secured thereto, a U-shaped lever pivoted to the protrudingends of one of said straps, levers pivoted to the protruding ends of theother strap and pins pivoting theiirst mentioned levers to the secondmentionedlevers.
